It's a Monday, so let's start with something exciting:

alert tcp $EXTERNAL_NET any -> $HOME_NET 25 (msg:"SPECIFIC-THREATS 
UTF-8 BOM in ZIP"; flow:to_server,established; file_data; content:"zip"; 
content:"|EF BB BF 50 B4|"; metadata:policy balanced-ips drop, policy 
security-ips drop, service smtp; 
reference:url,http://blogs.mcafee.com/mcafee-labs/phishing-threat-uses-utf-8-bom-in-zip-signature-to-evade-detection; 
classtype:trojan-activity; sid:10000045; rev:1;)

Or not ;)..thoughts/cleanups/anything_that_would_make_this_useful are 
welcome.

James
